In case of headlight failure, what should you first attempt?

In the event of headlight failure, the most immediate and logical action is to try the high/low beam switch. This is because the issue might be as simple as a disruption in the headlight setting that can easily be remedied by toggling between high and low beams. Sometimes, a headlight can fail due to a malfunction in the switch itself rather than a bulb outage, so attempting to see if the headlights operate in one of the other settings can help determine if that is the case.

If the high/low beam switch resolves the issue, you can continue driving safely without the need for further assistance. If it does not solve the problem, this indicates a deeper issue such as a blown bulb or wiring problem, which would necessitate further action, like changing the bulb or seeking help. Therefore, addressing the switch first allows you to quickly assess the situation and potentially resolve it without unnecessary delays or complications.
